Application 110a new 2, 1926/ Serial- No. 113,291

This invention relates-to improvements in door fastening means, and has for its pri mary obye'ct lillOQl'OVlSlOll of fastening means ally for use in connection Withlarge movable doors of his type commonly found in connection with or the like and wherein the fastening means is of sinipleand novel form ca iable of bein' posit'ivel eet at a-3osition so as to hold an associated doorin a securely locked position and yet With corresponding facility to permit of the unlocking thereof. i V

In accordance with the invention my improved fastening" mechanism consists of an elongated rod mounted for-rotation about'a longitudinal and vertical axis in connection with fixed bearin gs carried by the'inner Wall of an associated door, the lovverend ofthe rod being provided Witha handle to effect its axialrotation, and the upperend of the rod being provided with a fixed eccentric member, and arranged for cooperation with a keeper memberfixed to and carried in connection with the door frame, the arrangement of the parts being such that when the eccentric is forced into frictional; engagement with the keeper member the door Will be retained in its closed or fastened position, and when the rod'is rotated to remove the'eccentric from frictional engagement Withthe keeper meniber tlic rod together With its eccentric is allowed to drop or fall to a position out of registration with the plane of the keeper member thus allowing the door to be swung or otherwise moved to an open position Withmechanism. p

lViththese and other objects in View, as

Will appear as the description proceeds, the

invention consists inthe novel featuresof out interference on thepai't of the fastening construction, combinations of elements and Figure?) is a horizontal cross-sectional i View on the line 33 of Figure 2,

Figure 4 is a detail sectional view showing the lock n connection with a floor member.

Referringm ore particularlyto the drawings the numeral 1 designates a door of suitable form, purpose or type. lior present purposes it may be said that'the door 1 is used in connection With the door-way of'a garage or other similarbuildingand is suitably mounted, for example, inconnection with hinges, so as to be capable of being moved to assume the positions either open} ing or closing the door-Way. The door is mounted in connection with a suitable, type of door frame 2, which latter in thisinstance is recessed asat'3 to receive the edge of the door and provide a stop to limit its inward or closing movement.

Mounted upon the "inner Wallof the door are bearing brackets 4;, preferably formed.

fromfca'stings so as to provide'base'pertions 5 Which are secured in a. rigid; manner tothe lIlDGPWiLll of the door. .Tlie oute'r" portions of'the horizontally and laterally extending brackets 4 are provided With bores 6, which are adapted 'to rotatably'receive a vertically extending shaft or red section 7,-

in'order that said section may beretained in 7 connection with the doorfor bot-h sliding and'rotatable movement. 1 r y p In this instance theupper end ofthe shaft or rod section 7 is formed .or provided With a fixed eccentric-8, arranged for rotation about the vertical axis of the shaft section r with a ,fixed keeper member '9 which, prefincludes a horizontal "base wall 10 suitably and in a substantially horizontal plane. -lliis eccentric is adapted for cooperation erably, is formedfroin a metallic castingand secured as at 11 in connection'with 'the upper portion of the door frame 2. *Furtheig'thcl kee iei't member is provided Wltlla chamber 12, having an open rear side and a short,

lower horizontally disposed Wall 13,

slituting a locking shoulder.

con-

lln operation. it ivillfibe seen that by ro-' tating the shaftor rodsection 7; and this 'may be conveniently accomplished by pro riding the lower end of said section with an out-turned horizontally disposed handle,"

14, rotary'movement ivill be imparted to the eccentric 8. This results in bringing that portion of the eccentric which possesses the smallest radii With respect'to the axis of the shaft section'in re istration With the Wall 13 of the keeper member. Inasmuch as tlie-eccentric is proportioned so tliatlwhen the" shorter radii. thereof is presented {to ,the

keeper member there Will be no frictional i keeper inemb r.

' tion contact of the eccentric with said keeper member, and the rod section will be permitted to drop, so that the eccentric proper will rest upon the upper surface of the upper bearing bracket 4, in a plane belowand independent of the iiXed keeper member 9. Obviously, this permits the associated door to be opened and closed at will without interference of any kind from the fastening mechanism. To fasten the door the reverse procedure is followed, wherein the shaft Sec 7 is elevated to bring the eccentric into registration with or in the plane of the Then by rotating the shaft section that portion of the eccentric possess ing the largestradii is moved into the chamber i2'above the wall 13 and frictionally sustained and held in engagement with said keeper member so as to positively fasten, the door inconnection with the jamb or. frame 2. It is of course within the scope of the invention to substantially reverse this con struction andlock the door in connection with the floor or lower part of the door jamb rather than in connection with the upper part thereof.

This fastener is not and cheap in construction, but may be =readily operated and performs its several arts are em )loved.

functions in a positive manner without structural complication such as is apt to be presentwhen springs and other multiplied It will be observed upon reference to Figure 3 thatfl when the eccentric occupies its locked position the same isswung past the center line indicated by the line.a-a, so that the handle 14 will engage the inner surface ofthe door. This position is permittedfdue to the fact that the upper end of the rod? may spring a trifle so .as to produce a resilient action or spring pressure on the eccentric. This results in ositivel ma int'ainin the eccentric in its 1 y r;

locked position, preventing undue rotationthereof after manual release.

To release the door positive pressure isrequired to rotate the eccentric so as to bring the same past'the only extremely simple .1-

j "The combination with a fixed frame and center line a-a. The eccentric is prefer ably provided with a socket in which the tapering and squared upper end of the rod The cotter pin or or shaft 7 is positioned. the like may be employed for retaining the eccentric on the end of the shaft. This construction permits of the reversal of the posi tion of, the eccentric so as to adapt the same tooperating positions either on the top or bottom of the door. In Figured thedevice has been shown as mounted on the bottom I the elevating influence of the spring 19. Of. course, a shoulder or lip may be used n 'tlllS' form of the construction if desired. What is claimed is ings carried by the inner wall of said closure member, an eccentric provided upon the upper end of said shaftsection, a keeper,

member carried by the fixed frame and" formedwith a chamber for the reception of a said eccentric so to frictionally engage that portionof said eccentric possessing the greatest radii with respect to the longitudinal axisof said shaft section, and a wall formed with said chamber and arranged to underlie a portion of said eccentric when the latter occupies said chamber and, to

clear said eccentric when the said eccentric is. out ofengagement with said keeper.

In testimony whereof I afiix my signature.
